I am looking to install a TCS Fleetlighter in the unpowered end of a Bachmann 158 in order to control the lights. I have used a Lenz decoder in the powered end connected as per Steve Jones' advice at:

This works well without any change to the resistors on the lighting circuit board. The TCS page at:

however, suggests that the 470 ohm resistors on the lighting board be replaced with 1000 ohm versions. Is this strictly necessary? The output of the functions is rated at 250mA so if the DC voltage was 16V, minus 1.4V for the LED, this would give a current of 31mA which is well within the scope of the max output current.Or am I missing something obvious?
